"Inland" Manufacturing M1 Carbines - 1st hand experience

And... if the soft bolt fails, the pistol version is at arms length, minimizing the possibility of injury....

New to this forum (mostly stay on the CMP board) but I've been reading this thread and the news is really disappointing

Really makes one appreciate the various contractors that did things correctly under wartime pressures

Its been about 6 weeks since I returned the 2nd carbine, the one sent as a replacement for the one I purchased. No word yet.

Welcome to Milsurps.
You are quite right. Given the pressures of war, the difficulty converting from civilian to military production (IBM always amazes me) and the shortage of supplies, the criticality of quality control, the complexity of the supply chain, and the need to use new machinery, it is just remarkable how we could build weapons -- not just M1s, but tanks, ships, and planes. It is grand testament to the power of teamwork and an aligned nation.

During WW2 there were a LOT of people who had worked as machinists and metal guys. Welders, sheet metal men, etc. Most people who work with metal understand it and know what works. I suspect that the guy who can crank up a lathe and make a part without a high scrap rate are few and far between today. Parts are injection molded today and lathes are CNC controlled to keep scrap rate low. I'd bet that this is part and parcel to why we see poor heat treatment and failures that are simply unacceptable.

We are now halfway through Feb, have you heard anything from Inland? Still wondering if they ever solved the soft bolt problem.

I've been bogged down in work that's kept me away from the carbine research and websites I prefer to do. My apologies for the delay.

I received another replacement from Inland which I picked up after the January Shot Show in Las Vegas. S/N is 9001837. I also picked up a new Auto Ordnance carbine to compare the two. S/N is MC5439.

The Auto Ordnance was returned to the manufacture to correct problems with the fit of the stock and handguard. It was back several weeks later. The handguard was sanded down to fit flush with the stock but the stock was machined at an angle causing the action to sit an an angle in the stock. Most evident in the barrel channel where the barrel sits at an angle. Termite damage in the handguard was acceptable to Auto Ordnance.

Again, these pics are an Auto Ordnance carbine stock and handguard. Which Inland alters before selling.

Inland doesn't alter the inside of the stock and their barrels also sit an an angle in the barrel channel. To varying degrees. Some worse than others. Inland doesn't try to correct this as it would make the fit worse. It's an issue with the manufacture of the stock.

First, the comparison of the Inland to the Auto Ordnance. With the exception of the rear sight (adjustable on the Inland, flip sight on the AO), barrel band (with lug on the Inland, type I on the AO), wood finish (darker on the Inland, too light on the AO) and the use of the round bolt by Inland vs the flat bolt by AO, they are the same parts and the same carbine. Not similar, the same. The bolt is also the same with the Inland simply not having the lightening cut in the top of the bolt.

At the Shot Show I spoke with Inland's president, Ron Norton, who indicated he gets the Inland stocks from Auto-Ordnance and has had the same issues with the quality and fit. His people do the sanding to ensure a proper fit of the handguard and stock before they stain the wood darker.

One buyer noted previously the replacement stock and handguard they purchased from Inland would not fit their non-Inland non AO carbine without modification. Which is still consistent to varying degrees with both the Inland and AO wood. At the Shot Show I examined the Auto Ordnance carbine on display and found the handguard fit flush with the stock on the left side but extended out past the stock on the right. With the offset barrel position in the barrel channel. Anyone holding the AO carbine would feel the sharp edge of the right side of the handguard protruding out from the stock. The degree to which it's offset varies a little.

At the Shot Show I also learned from several sources, including the stock manufacturer, that the stocks for Auto Ordnance and therefore Inland are made by the Altamont Company in Thomasoboro, IL. They have also been making the wood for the AO and Inland M1A1 stocks but stopped recently. Apparently the source for the metal parts for the M1A1 stock is no longer available and both AO and Inland are seeking a different source.

There have been two other issues with the AO stocks. The nose at the front of the stocks, for whatever reason, are not rounded as all other carbine stocks. Altmont leaves them flat at the front. The second is the sling cut. Altmont doesn't machine the slingcut properly. This leaves about a 1/16" drop from the left side of the stock into the front of the slingwell instead of being smooth. Minor, but odd. But they also don't machine the angle properly which inhibits the use of an oiler to hold the sling in place. Norton indicates Inland rounds the nose before staining and cuts a semi circle in the slingwell to allow the oiler and sling to fit. Auto Ordnance leaves these issues as acceptable. I had requested, in writing, they be corrected when the stock was returned. They weren't. Several years ago with another Auto Ordnance I found a plugged knot hole in the stock and other unplugged knots. AO indicated not accepted for return as they didn't impact function. They have since indicated this on their website under returns, but not in the carbine description.

Attachment 70108

Back to the Inland, and also found on the current production Auto Ordnance carbine. Neither bolt is machined to GI dimensions. The right lug is shorter on the AO and Inland than the right lug of a GI bolt. I missed this before. The machining of the front and rear of the Inland bolt's right lug is slightly different than that of the Auto Ordnance. The front of both lugs have minor damage from the test firing by the manufacturer(s) and probably the operation of the slide/bolt action. Neither has been fired yet as both bolts appear to be "soft". Before firing either carbine I'm going to have a heat treatment facility do an Rc test on the right lug of each bolt. Unlike the previous Inland bolt, neither bolt has evidence of an Rc test by the manufacturer(s). Having the hardness test done has been put on hold due to work commitments.

The headspace of both carbines is as it should be, unlike the last Inland. The issue with the trigger spring hole in the rear of the trigger housing being flat on either side still exists, in both carbines. The issue with the casting of the receiver leaving imperfections inside the receiver in the path of the bolt still exists, in both carbines. However, unlike the other two Inlands that were not machined smooth inside the receiver, both of these carbines have had the ridges of the imperfections smoothed. Neither receiver has been machined along the top right where the slide travels back and forth. This leaves an uneven surface for the slide to travel on and over, removing the finish from the receiver in this area. This issue has been noted on all of the receivers used by Inland and Auto Ordnance. The magazine catch of the Inland is somewhat loose in it's slot in the trigger housing and wobbles when used. Not so the Auto Ordnance. Since I haven't examined a number of AO carbines of recent manufacture this may be consistent with the rest of the lack of uniform quality control that has been an issue with the AO carbines from the start, and now inherited by Inland.

Both the Inland and Auto Ordnance are parkerized with manganese phosphate. All Inland's I have owned and examined the finish is easily scratched and wears off quicker than I've experienced with no other guns but those by Chiappa. Chiappa's finish is different. The Auto Ordnance fairs better with wear and scratches. I have no idea why, not an area I'm fluent in.

One other thing that's extremely important. The gas piston nut on this Inland, the previous Inland it replaced and this Auto Ordnance carbine were not tightened before they were staked and not staked sufficiently to keep them from rotating out. Should this happen it will effectively redirect the energy away from the rear of the bullet and into the rear of the gas piston, making the gas piston the bullet. The slide will catch it but the transfer of energy to the slide is not something you, or anyone near you, will want to experience. Before you fire a carbine made by either of these companies, and/or any used carbine you buy, make sure the gas piston nut is tight and staked properly.

I do not know what kind of arrangements or agreements Inland has made with Auto Ordnance. What I do know is their part numbers are the same, their model numbers are the same but for the AO on Auto Ordnance and IN on Inland, their manuals are the same but for the name and address of the manufacturer, and all of their parts are identical except the differences noted above. Same casting mold marks on the cast parts, receiver included. Same cast parts, same milled from forged steel parts.

At this point in my own experience with the Inland carbines and feedback I've received from more than a dozen other Inland owners, after examining this current Inland I don't need to shoot it to see if the issues with the bolt have been corrected.

Last but not Least

My web page on Inland will be completed when I can find the time. It will include advising owners to monitor the wear of the rear of the bolt and the right bolt lug as their lifespan will not be that of a GI bolt. Every part on every carbine, and every firearm, has a lifespan. Commercially manufactured bolts have consistently not been hardened to GI spec that requires the rear of the bolt be harder than the front of the bolt so all commercial bolts should be monitored for wear on the rear of the bolt. For Auto Ordnance and Inland I'll be adding the right bolt lug needs to also be monitored.

I will also be indicating GI parts may or may not be interchangeable with those of the Inland and Auto Ordnance carbines due to variances in quality control and machining, or a lack thereof, that may make their parts not to GI spec.

I realize Inland has made a number of claims as to changes and there has been evidence of this. But the issues with their bolts, even after whatever changes they have made, remain. They are not inherently unsafe but they need to be monitored to keep them safe.

On my websites and web pages I don't get into value and prices. People buy what they want and can afford which is what has driven the market for the new and used commercially manufactured carbines. But here I'll make the following observations and suggestion....

The $250 or so more for the Inland carbine buys you an adjustable rear sight instead of a flip sight, a more secure barrel band, one less cut in the bolt, a darker finish, a few wood modifications that are an improvement over the Auto Ordnance carbine and the Inland name instead of the Auto Ordnance name. But they are the same carbine otherwise.

There are currently 5 manufacturers making new M1 Carbines. Auto Ordnance, Inland and Classic Carbines are the low end in quality and price. They'll work, but if you plan on shooting a lot the cost in replacement parts alone may reach into the two manufacturers at the upper end, James River Armory's "Rock-Ola" reproduction and Fulton Armory. Of these two, the Fulton Armory carbine is better built and well worth the few extra dollars. Wait to buy until they run one of their holiday sales. Of the 5 the one with the highest quality is Fulton Armory.

If the cost of a new carbine is an issue don't feel alone. Used GI carbines are still readily available as are used commercial carbines. But don't be fooled by whoever made either one as they are all used carbines and there is no way to know what they've been through. Looks can be deceiving and claims should have hard evidence to support them. If you buy a used carbine, regardless of who made it and when, get it safety inspected before you shoot it. The design of semi-auto military rifles and the rifles that copy that design come with the need to monitor several things that can become safety issues. Head space is right at the top of that list. The safety inspection doesn't cost much for what you get in return.

Thank you for your latest observations. It's a shame these companies won't fix these known problems.

Thought this was an interesting little read on cast vs forged vs billet parts:

I would guess it is just like a new car model, on its 1st couple of months, hiccups. Be interested in seeing a latter built gun, and see if they have fixed the problems.
